    Hi all,

    in case the AOS service is running, axc configuration is correct and you still face the issue, you should check the table sysserverconfig as it may contain old AOS entry

    RE: AX Installation error " Connection with the Application Object Server could not be established"

    Hi All,

    I was facing the same issue, i found out the solution for this, it worked for me.

    I had installed AX 2009 AOS in my local system. And client in other' system pointing to my local system AOS. If i open the AX, in which system i have installed client, i was getting Connection with the Application Object Server could not be established" error.

    Solution is : 1. Both user should be in the same domain, means in which system we will install AOS and in which we will install client both user.

    2. The main issue is, there was no communication between the systems, like both can ping and can access one another's ip address and host name.

    For this i just turned off my windows firewall in both the systems and checked, then if i open AX, it was working fine. And later i added AX setup to the Trusted application in control panel and turned on the Windows firewall.

    Hope this will help for you guys also. . :)

    Check connectivity with your AX AOS service server.

    Check installed client port number is matched your AOS port number

    check if you are using multiple AOS you configured your client to refer to which AOS port and Name

    Check Ports number is configured on your Servers firewall.

    It is network problem and you can solve it.

    Open host file (c:\windows\system32\drivers\etc\hosts) on the AX Client PC or Terminal Server. Add IP address of AOS server and AOS server name

    192.168.1.25     AOSServer

    in host file then Run the command nbtstat-R and start Dynamics AX Client.

    A pure network/ administrative person can think here better than us AX guys.

    Let's see if somebody with that capacity shares some optimal approach to resolution and reasoning

    I am able to ping the AOS server, even desktop users are also able to use with out any difficulty, The problem is only with laptop users, It sounds funny but really I am facing this situation.

    AOS is running and it is on other machine, the other thing is this that the problem is with only laptop users, for desktop users its fine.

    Can you ping the AOS server from the client machine? You should be able to ping the servername (without having to use FQDN) if ICMP-traffic is allowed and ping is not blocked by a firewall.

    Do you have multiple versions of AX client installed on the machine? You may experience the same "error" if it attempts to connect to AX using the wrong version of the client (like connecting AX2012 with AX2009 client).

    Please tell us more. Is your AOS running? Is the port open on Firewall if AOS is on a remote machine? And so on.

    check you AOS service in windows Services if that is started or not yet

    if not started yet and is in Starting state, wait until it is running, after that start client.
